Flash photolysis of dimethyl oxalate produced the radicals CH3, CH30, and COOCH3. Thermally equilibrated methoxycarbonyl radicals did not decompose during radicalradical reactions in the presence of 40-tom cyclohexane in the temperature range 298-448 K. Cyclohexyl radicals were also generated during
